Chemistry - CHEMICAL BONDING Question with Solution | TestHub

In all the given species, the central atoms involved in multiple $\pi$ bonding are sp hybridized, which leaves two unhybridized $p$-orbitals (such as $p_y$ and $p_z$) that are mutually perpendicular. Since each $\pi$ bond is formed using one of these orthogonal orbitals, the resulting $\pi$ bonds and their respective nodal planes are oriented at $90^{\circ }$ to each other. This geometry is a characteristic of linear systems with triple bonds or cumulated double bonds, making A, B, C, and D all correct.
